Marine Damage Surveys & Boat Damage Inspections in San Diego
Great River & Lakes – Marine Surveying Co. provides professional marine damage surveys and boat damage inspections in San Diego, California for vessel owners, insurance companies, attorneys, lenders, marinas, repair facilities, and other parties requiring independent documentation of vessel damage.

What Is a Marine Damage Survey?
A marine damage survey is an independent inspection performed to document the observable nature and extent of damage to a boat or yacht.
Depending on the assignment, the surveyor may document:
Areas of visible damage
Structural damage
Hull damage
Machinery damage
Electrical damage
Water intrusion
Damaged equipment
Affected vessel systems
Observable pre-existing conditions
Recommended additional investigation
Repair considerations
Photographs and supporting documentation
The exact scope depends on the casualty, vessel type, accessibility, and requirements of the client or insurance company.
Insurance Claim Boat Inspections in San Diego
Great River Marine Surveying provides insurance damage claim surveys for boats and yachts throughout San Diego.
A marine insurer may request an independent survey after a loss to help document the condition of the vessel and the extent of observable damage.
We can assist with claims involving:
Collision damage
Groundings
Docking accidents
Storm damage
Fire damage
Flooding
Water intrusion
Machinery failures
Propeller and running-gear damage
Transportation damage
Marina incidents
Impact damage
Our surveyor documents observations independently based on conditions accessible at the time of inspection.
Collision Damage Surveys
Boat collisions can affect far more than the immediately visible exterior surface.
Depending on the location and severity of an impact, damage may involve:
Hull laminate
Frames and structural members
Bulkheads
Deck-to-hull connections
Rub rails
Swim platforms
Running gear
Propellers
Shafts
Rudders
Steering systems
Interior components
A marine damage inspection can help document both visible impact areas and accessible surrounding structures that may warrant additional evaluation.
Grounding Damage Inspections
A grounding can damage underwater components even when relatively little damage is visible above the waterline.
When a vessel has grounded, inspection may include accessible portions of the:
Hull bottom
Keel
Propellers
Shafts
Struts
Rudders
Saildrives
Outdrives
Trim tabs
Through-hull fittings
Transducers
Structural attachment areas
Haul-Out After a Grounding
A haul-out is often appropriate following a grounding because underwater components cannot be adequately evaluated while the vessel remains afloat.
Where practical, our surveyor can coordinate the damage inspection with the vessel's marina or boatyard so the underwater hull and running gear can be examined.
Storm & Weather Damage Surveys
Southern California vessels can experience damage from wind, waves, heavy weather, dock impacts, line failures, debris, and other environmental events.
A storm-related marine damage survey may document:
Hull damage
Deck damage
Broken hardware
Damaged railings
Window or hatch damage
Water intrusion
Rigging damage
Docking damage
Electrical problems
Machinery exposure
Interior water damage
The survey report documents observable conditions present during the inspection.
Fire Damage Surveys
Marine fires can affect structural materials, wiring, machinery, plumbing, fuel systems, interior components, and surrounding equipment.
Depending on accessibility and the requested scope, a fire damage survey may document:
Areas of direct fire damage
Heat-affected components
Smoke damage
Electrical system damage
Machinery damage
Structural concerns
Interior damage
Fire suppression equipment
Areas requiring further specialized evaluation
Fire-damaged vessels may require additional inspection by electrical, mechanical, structural, or fire-investigation specialists depending on the circumstances.
Water Intrusion & Sinking Damage
We provide damage surveys for boats and yachts affected by flooding, partial sinking, complete submersion, leaking systems, or other forms of water intrusion.
Potentially affected areas may include:
Engines
Generators
Electrical systems
Batteries
Electronics
Fuel systems
Interior finishes
Machinery
Pumps
Wiring
Structural components
Prompt documentation can be particularly important after significant water exposure because vessel conditions can continue to change after the initial casualty.
Machinery Damage Surveys
Marine damage is not limited to the hull.
Depending on the assignment, our surveyors can document observable damage involving:
Engines
Transmissions
Generators
Propulsion systems
Steering equipment
Cooling systems
Exhaust systems
Electrical equipment
Pumps
Auxiliary machinery
Specialized engine technicians or other technical specialists may be recommended when manufacturer-specific diagnostics or internal mechanical evaluation is required.
Propeller, Shaft & Running-Gear Damage
Propellers, shafts, struts, rudders, outdrives, and other underwater components can be damaged by groundings, submerged objects, debris, fishing line, dock incidents, or other impacts.
A haul-out inspection may allow the surveyor to document:
Propeller damage
Shaft damage
Strut damage
Rudder damage
Outdrive damage
Trim-tab damage
Visible alignment concerns
Hull damage surrounding running gear
Damaged through-hull components
Additional mechanical or alignment testing may be recommended based on observed conditions.
Dock & Marina Damage Inspections
Damage can occur while a vessel is secured at a marina as a result of:
Dock impacts
Neighboring vessels
Failed dock hardware
Line failures
Wake damage
Wind events
Electrical incidents
Marina equipment
Falling objects
Other dockside events
Our surveyors can inspect vessels at accessible San Diego marinas, docks, boatyards, and repair facilities.
Transportation Damage Surveys
Boats and yachts can also be damaged during overland transportation, loading, unloading, launching, lifting, or storage.
Transportation-related inspections may involve:
Hull impact damage
Scratches and abrasions
Structural concerns
Damaged rails or hardware
Propeller or running-gear damage
Trailer-related damage
Lifting-point damage
Interior movement or equipment damage
Photographic documentation and timely inspection may be valuable when multiple parties are involved.

We also provide marine damage inspections for sailboats.
Depending on the casualty and accessibility, damage inspection may include observable portions of:
Mast
Boom
Standing rigging
Running rigging
Chainplates
Deck hardware
Steering systems
Keel
Rudder

Center consoles

Performance boats
Multi-engine yachts
Larger vessels may require coordination with boatyards, mechanics, electricians, fiberglass specialists, or other marine professionals depending on the damage involved.
What Does a Marine Damage Survey Report Include?
Depending on the requested scope, a professional damage survey report may include:
Vessel identification
Date and location of inspection
Description of reported incident
Areas inspected
Observable damage
Photographs
Relevant vessel conditions
Recommendations for additional investigation
Repair-related observations
Supporting documentation
The report is based on conditions observable and accessible during the inspection.
Does a Damage Survey Determine Insurance Coverage?
A marine surveyor documents the vessel and observed damage.
Decisions regarding insurance coverage, policy interpretation, liability, payment, or legal responsibility are made by the insurer and other appropriate parties rather than by the vessel survey itself.
The survey provides independent technical documentation that may assist those parties in evaluating the claim.
Damage Survey Before Repairs Begin
When practical, having the damaged vessel inspected before substantial repairs begin can help preserve documentation of the original condition.
If emergency repairs are necessary to prevent further damage, owners should retain photographs, invoices, damaged components when practical, and other relevant documentation.
The circumstances of each casualty are different, so inspection timing should be coordinated with the insurance company and repair facility when applicable.
